PRINTING-T ELEGRAPH.

SPECIFICATION forming part of Letters Patent No. 257,877, dated. May 16, 1882.

Application filed February 6, 1882. (No model.)

To all whom'it may concern Be it known that we, J. HOLMES LONG- sTREET, a citizen of the United States, residing at Hoboken, in the county of Hudson and State ot New Jersey, and JOHN E. Wnrenr, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certainv new and uscful Improvements in Printing-Telegraphs, of which the following is a specilication.

Our invention relates toprintingtelegraphinstruments inwhich separate electro-magnets are used for operating the type-wheel escapement and printing Or impression mechanism respectively, said magnets being connected in separate line-wires; and it relates especially to that class of instruments intended for printingstock and other market quotations, and` similarmatter in which letters and Arabic numerals are combined in approximately equal proportions. y K

The object of our invention is to increase the speed Ot receiving messages by'such'instruments, and to simplify their construction and operation; and to this end it consists mainly in a novel combination ot' two typewheels'txed upon the same shaft, one bearing letters simply and the other numerals, an inA dependently-operated printing-pad or impression device for each type-wheel, and devices for feeding to said wheels a fillet ot' paper or other suitable material wide enough to receive impressions from both wheels'without neces- 'sitatinglateral shifting ot` any ot' the parts for that purpose, the impressions being formed in tWo rows, letters in one row and numerals in the other, as will be hereinafter particularly described. It also ,consists in an electro-magnet composed of' a permanent magnet having one of its poles bifurcated to form 'two cores, upon which are arranged separate helieesjof insulated wire, and two armatures pivoted to the other pole and arranged to be acted upon by said cores respectively, in combination with two printingpads connected with said armatures respectively, and two type-wheels arranged to receive pressure from said pads respectively, the arrangement of the coils being such that their cores will be respectively neutralizedor partially neutralized temporarily by electric currents ot' opposite polarity or direction.

. Ourinvention also comprises certain novel details of constructiomwhich will be hereinafter fully described, and pointed out iu the claims.

In the accompanying` drawings, Figure 1 is a perspective view of a printing telegraph-instrument embodying our invention. Fig. 2is a side elevation thereof'. Fig. 3 is a plan view of the same. Fig. 4. is a detail view ofthe unison devices. Fig. 5 is a detailpersl'lective view of the escapement mechanism. Fig. 6 is a diagram illustrating a transmitting apparatus suitable for use in connect-ion with our improved instrument; and Fig. 7 is a view ot' a lillet printed by the instrument.

rlhe unison devices and escapement are the same as shown and described in our Letters 7o Patent No. 245,732, granted August- 16, 1881, but somewhat ditferentl y arranged. p The letters A and A designate two typewheels, xed upon a common shaft,"a, geared to a driving-train, and provided with `an eseapement-wheel, I), the movement of which is controlled by au anchor escapement-pallet., c, vihrated by a polarized electro-magnet. The only difference between this escapement and that inv our patent above referred to is that the helices ot' the polarized magnet and the escapement-'pallet are here arranged below the escape-wheel, whilein said patent they are arranged above,`and a further description "of these devices is therefore unnecessary.

The letters D and Dl design-.tte the helices, the cores ot which control the armatures Eend E', to which are connected the printing-pads F and F respectively, by means of armsj and j", to the outer ends of which said pads are pivoted. The armatures are drawn upward for .printing by means of springs g and g' connected thereto, and to an arm, g2, projecting laterally from the frame of the train, said springs being connected directly to suitable adjusting-arbors mounted in said'arm in the usual manner. The cores ofthe helices D and D are extensions or prongs ot' one biturcated pole of a permanent magnet, H, (shown arranged below the base X nponwhich the in- IOO strument sits,) its other, pole having an extension, h, projecting upwardly through the base, and having pivoted in its upper vedge the armatures E and E', upon steel pivots secured in said projection. The armatures extend rearwardly somewhat beyond the'projection h, so as to come under adjustable stops t' and i', arranged in brackets attached to said projection, these stops serving to regulate the downward movement of the armatures. To the rear of the extension h of the magnet H each of the armatures has rigidly' connected to it a. vertical rod, as shown at cand 7a', these rods at their upper ends being hooked over a shaft, l, the hooks normally embracing, withouttouchin g, pinsm and m respectively, which project upward from said shaft. This shalt l has its outer bearing in the bracket n and its inner bearing in the frame of the machine, projecting through said frame, and having fixed to its inner endan arm, M, by means of a co1- lar, m2, said arm M being shown in dotted lines, Fig. 3, and in full lines in the detail view, Fig. 4. Said arm is bent at its free e-nd to form a finger, m3.

' L (shown in Figs. 3 and 4) is a ratchet-wheel attached to a slowly-moving shaftot' the train which impels the type-wheel, and moves continuously in the direction indicated by the arrow. Fitted loosely to the same shaftis the locking-arm P of the unison-stop mechanism, having a finger, p, bent laterally at its end, and R is an arm fixed to the type-wheel shaft a, and which engages with the tingerp of the arm P when the latter is raised at the proper point.

Pivoted to the'arm P is a gravity-pawl, S, which tends to constantly engage with the ratchet-wheel L, thus locking the arm P to the train and causing it to be lifted toward a point where it will lock the type-wheel shaft. lThe pawl S is provided with a curvilinear extension, t, against which the finger m3 of the arm M strikes whenever either of the printingpads is operated, thus disengaging the pawl from the ratchet-wheel L and allowing the arm Pto drop back by gravity to its startingpoint. The curvilinear extension t at the same time slides upon finger m3, and the pawl is thus prevented from re-engaging with the ratchet before the arm P has completed its downward movement.

It will be seen that when either of the armatures E or E rises to operate its printingpad its rod 7c or 7c will be swung rearward, and the hook at the top of the arm, whichever it m'ay be, will strike one of the pins m or m', thus giving the shaft Z apartial rotation, which throws up the arm M, so that its finger' will strike the curvilinear extension t of the pawl S.

The operation of the unison devices from the arm M to the armv R on. the type-wheel shaft is the same as in our patent heretofore referred to; but the devices for giving a partial rotation to the shaft differ from the devices for the same purpose shown in said patent, as here we operate said shaft from either o'f two printing-armatures, whiie in said patent it is operated by the vibrating tubular core of the printing-magnet.

It will be understood that when the train is wound up the escapement-wheel b has a constant tendency to move forward in the direction indicated by the arrow and move the typewheels in ythe same direction, and that by sending reverse currents over the helix B the tubular core a and pallet c will be vibrated to allow any desired letter orfigure of either of the type-wheels to be broughtinto proper position for printing upon the fillet. Said fillet may be brought from a reel preferably located below the table or base, passed over both the pads Fl and F, and thence over the drum Q, as shown in dotted lines, Fig. 2. Each of the armsfandf has fixed to its tip beyond the printing-pads a bracket, o, and to these brackets atc pivoted toothedpawls u, the toothed ends of which are forced toward the drum Q by suitable springs, so that either of said pawls, when raised by the arms to which it is connected, will slip over the fillet on the drum, and when again depressed its teeth will take into said fillet and move itA forward on the drum. Now, supposing that a certain letter is to be printed on the fillet and a certain numeral at'ter it, the type-wheel shaft, by sending reversed currents through the helix B, is rotated sufficiently to bring the proper letter of the wheel A into position for printing, then a proper current is sent through the helix D to neutralize, or partially neutralize, the magnetism of its core, and the spring g will raise the armature E and its arm fand thus drive the pad F upward to press the fillet against the letter. In the meantime thel armature E is held down firmly, for though the helices l) IOO and D' are to be connected in the same linewire they arc wound in different directions about. their cores, so that a current which neutralizes, or partly neutralizes, the magnetism of the core of one helix re-enforces the magnetism of the other core. The letter having been printed by the action of the armature E and the circuit broken, so that said armature is again attracted by the core below, the escapement is again operated to bring the desired figure of wheel A into position to print, and then a current of suitable polarity or direction is sent over the helix 1) to neutralize, or partly neutralize, its core, so that the springg' will raise the armature E and its arm f', causing the pad F to press the fillet against the figure for printing. The printing-circuit being then broken the armature E is then again attracted by the core below, and the instrumentis again in condition to print either letters or numerals, as desired. 0f course several letters 0r several numerals may be printed in successionas, for instance, N Y C at one side of the fillet and l 9 8 at the other side, as shown in Fig. 7. As each armature descends the feed-pawl feeds the paper along properly to receive the IIO Y and Y' a main-line battery at the sending-sta- 257,877 j y s next impression. A frame, N', prevents the side of the llet which is not to be printed upon from being carried against the typewheel above it and blurred. Theink is supplied to the type-wheels by ink-wheels 'v2 in the usual manner. i

In the diagram Fig. 6 we have illustrated a transmitting apparatus and shown the arrangement of line-Wires and batteries which may be used in operating our improved instrument. In this diagram B designates the escapement-magnet and D and D' the helices of the printing-magnet. W is the line-wire oper ating the escapemeut, and W' the line-wire t'or operating the printing mechanism. Y is alocal tion. The letter M2 designates an electro-magnet included in the circuit of the local battery' Y, one terminal ot' said circuit being connected with a break-wheel, V, the makes and breaks ot which are equal in number to the characters on one of the type-wheels. The other terminal ot' this circuit connects with a metallic spring-iin ger, which bears upon the periphery ofthe break-wheel, which is supposed to be constantly revolving by means of suitable mechanism. From the shaft of this wheel projects an armyu?, and V2 represents one ofthe keys of the key-board, either of which may be pressed down in the path of the arm v raud stop the' is elect-ricallyconnected with the stop 9', and

the other pole is connected with the stop 9. The finger a2 is connected with the ground and the inger n3 with the line wire W," which is connected with the escapement-helix B. The stop i S' is connected-with the stop 9. When thengers u2 and a2 make contact with the stops 8 and 9 respectively a current tlows from the positive pole of the battery to stop 9, and

thence over the finger n2 and the line-wire,

and at the same time a currenttlows from the ground to finger a2 and over stop 8 and the connecting-wire to the negative pole of the battery; but when the tin ers make contact with the opposite stops, S' nd 9', the current flows from the positive pole to stop 9, thence to stop 8', and over finger a2 to the groundwire, while at the same time a current tlows from the line-wire W to finger a2 and thence over stop 9' and the connecting-Wire to stop 8, and-thence to the negative pole ofthe battery.

As the break-wheel is in constant rotation, except when stopped by a key, the lever m4 is in similarly constant vibration, and thus a succession of reverse currents are sent over the line-wire W while the transmitter is in operation, resulting in the step-bystep rotation of the escape and type wheels ot' the printing-instru men t, as heretofore'described When a key 7oV of the key-board is depressed it will be struck by the arm o and the break-wheel will be stopped. As it starts from a point" in unison with the typcwheels,the depressed key will designate the letteror numeral which is slipped into position to print.

The letter Y2 designates the printing-battery, the opposite poles of which are connected with anvils under the keys 10 and 10', both ot' which are connected with the line W', which' 8o is connected with the helices D and D', the cores ot' which control the printing-armatures E and E ofthe printing-instrument, the middle ot'thebatterybeingconnected to theground.

When a key of the key-board is depressed to Q stop the type-wheels one of the keys 10 or 10' is to be depressed immediately after to cause the operation of one ot' theprinting-armatures. Which of the keys l0 or 10' is to be depressed and D', with respect to the neutralization, or partial neutralization, ot' their cores, and whether a letter or numeral is to be printed. it' a current in the direction of the arrows No. l

depends upon the arrangement of the coils D 9o neutralizes the core of the helix D, and a let- 9'5 core ot helix D is neutralized, andl its arma- Ico ture flies up to print, and if a current in 4the direction of arrows No. 2v neutralizes the core' of helix D' and a numeral is to be printed, then the key `10' is to be depressed, anda eurrent will iiow over the wire W' in the direction ot' arrows No. 2 to the negative pole ot' the battery.

While this diagram illustrates the general principle ot' a transmitting apparatus adapted for use with one g'iriutinginstrument, we may use any other form which will cause currents to tiow sitnilaily over the line-wires.

We are awurethat printing telegraph instruments have been provided Wit-h two typcu wheels upon the same shaft, one hearing let-- ters and the other numerals; butin every such instrument known to useither the type-wheels must be shiftedlaterally to a printing-pad or t a single printing-pad must be shifted to the ditferent type-wheels as a letter or numeral is to be printed, thus wasting the time in shifting, which in our instrument is utilized in printing immediately when the escapemen t-wheel is rotated far enough to bring the proper letter or numeral opposite its pad.

lu the modified construction ofthe appara tus shown in Flo'. 8 the attraction ot' the armatures by the magnets produces the impression, 4and the retractile springs simply act in the ordinary manner to remove the armatures from the cores, thus removing the pads from the type-wheels. The armature E2 IOS IIO

is-pivoted to the pole of the permanent magnet'nearest the type-wheel, and this armature and the pad-carrying arm f2 form a lever of the first kind, while in the machine as illustrated in Figs. 1, 2, and 3 each of the pad-carrying arms forms a lever of the third kind. The spring g2 holds the armature normally away from the core of coil D2, and when acurrent is sent over said coil the permanent magnetism ot' its core is re-enforced by the inductive influence of the current and it attracts thearmature, thus causing the pad to be thrown toward the type-wheel, pressing the fillet thereagainst. In this form of' machine the cores of the printing-magnets may be either of unmagnetized soft iron or permanently polarized. In the former case the letter H2, Fig. 8, may be considered to designate a bent soft-iron bar, while in the latter case it would indicate a permanent horseshoe-magnet, and in the former case the armatures would require to be permanently polarized, the helices being arranged to differently polarize their cores, so that a current in one direction would cause one core to attract and the other to tend to repel its armature, and a current in the opposite direction would produce a relatively reverse effect. In both eases the cores are f'ormed by extension of' one end of the metal bar, and the armatures are pivoted to an extension of the other end.

Only one magnet is visible in Fig. 8; but it will be understood that the other printing-inagnet is similarly constructed and arranged with .rela-tion to its armature and a pad-earryi ng arm,

which performs theim pression of the filletupon the other type-wheel, the type-wheels and all other devices, besides the magnets, armature, and pad-carrying arms, being constructed and arranged as shown in Figs. 1, 2, and 3.

The electro-magnet which controls the armatures for operating the 'printing-pads we intend to make the subject of a separate application for Letters Patent.

What we claim is- 1. Ina telegraphic priating-instrumen t, the combination, with two type-wheels and devices for rotating the same to and stopping them in desired positions, of a printing-pad f'or each 5o-type-wheel, separate armatures arranged to operate said pads, and two connected helices having permanently magnetic cores arranged to control said armatures respectively, the ar-5 rangement of said helices being such that. an electric current therethrough in one direction will neutralize, or partly neutralize, the core of one, while a current in the opposite direction will have a similar effect upon the other, substantially as described.
